91 302 Air Conditioning Prob.
Okay, since I know next to nothing about automotive ac I figured I would toss it out here and see what yall can come up with. I have a 1991 F150xlt, 5.0, E4OD, 2wd, reg cab. When I first turn on the AC after just a minute or 2 it blows ice cold. Then the compressor kicks out and the air out of the ducts warms up again, and the compressor doesn't kick back on. I just bought the truck about a month ago and didn't really mess with the AC when it was cold. By the way, the guy I bought it from said it was converted to 134A, and there is a sticker under the hood that confirms this, but I don't know what they actually did....please help, I'll die this summer without AC...

You might want to post this question in the other part of the forums that is devoted to heating and cooling. I'm sure you would get a good answer there.
I'm not an AC expert, but my past experience says usually when it won't cycle or cycles too quick, the system is low on freon. Since yours has been converted, it should not be a big deal to add some if necessary. Better check with the experts before doing it.

I have converted several systems over to the 134a
you can allways tell by the size of the inlet on the dryer, it should be larger.
and yes it sounds like it's low...
It's a do it yourselfer. they sell 134a with a gauge on it at the auto stores
I think it's like 10 to 15 bucks....
just read on the can and it will guide you through it......
Good luck and let us kno how it goes
